I just noticed that unlike many desktop calendars (such as the PandoCalendar I had on my old iMac), iCal has no library of holidays at all (much less holidays listed and installable by country or whatever). Any thoughts? Any solutions (other than the obvious, viz laboriously putting such in manually for the entire year)?

In PandoCalendar one can color-code the entries in a variety of ways, as well as specify holidays falling on variable dates (eg, Thanksgiving, Easter, Victoria Day).

I've got an OS X version: PandoCalendar 7.0.8

Part of the install instructions is:
Launching PandoCalendar at Login
To have PandoCalendar automatically launch when you login:
(1) Choose System Preferences... from the Apple menu.
(2) Click on the Accounts item.
(3) Click on the Login Items tab.
(4) Click on the + button.
(5) Locate and choose the PandoCalendar application.

If I do (1), I don't see any Accounts item. What's the score, anybody?

I've tried finding Accounts via EasyFind, etc ... to no avail, nothing pops up.
